embracing the tree and a simple yantra..

[...]

...or is it mudra?? You know.. Those little hand gestures you often find in yogic practices?

...I was thinking... You know the little gesture where you form a circle with your index finger and thumb... Does this have a similiar effect as embracing the tree? You are, afterall, simply creating a circle of flesh in both postures... But besides joining the meridians of the index finger and thumb, does it have the same qi culminating effect as embracing the tree?

 

.... I am imagining it does, though to a lesser extent. What do you guys think?
